摘要:
A process for a production of a vertical magnetic head. With this process of producing a vertical magnetic head, a magnetic spacer defining a head gap is formed. This magnetic spacer is formed from a same material as a substrate of the vertical magnetic head. Such a vertical magnetic head has particular application to magnetic recording and reproducing.
